Since, Both are in same plane φ= vec E ⋅ vec A =0

Q. A triangle surface of side $L$ meters in the plane of the paper is placed in a uniform electric field E (volts/m) acting along the same plane at an angle $6 0^{\circ}$ with the horizontal side of the triangle as shown in figure. The electric flux linked to the surface, in units of volt-m, is :-

Zero

$EL^ 2%

$E L^{2} cos θ$

$E L^{2} sin θ$

Since, Both are in same plane $ϕ = E \cdot A = 0$
